Yes, the backtick-comma is to downright hard-code it,
although it is code, and not a human, who do the
hard-coding...

Yes, that is clear, but this example shows (to me) the
difference between using hard-coded values and using
variables (in general).

That example looks all-fine to me. Are you saying, with
dynamic scope, the `i' in the lambda wouldn't have been
affected by the `setq'? But to me, your example is the
way it should be, natural... Why then, would you want
to use dynamic scope, and why is it the default?
